We were loving our 2006 jeep liberty crd, and the timing belt broke. Since it’s an interference engine, it’s destroyed. ☹️ now we just want someone to come get the car for parts. It's got a new transmission, a new transfer case, a new battery, a new tension, assembly and serpentine belt, a K&N filter, a green diesel reprogrammed computer, fairly new tires, new power, steering pump, front and rear brakes, rear shocks, alternator. It was our money pit! Would you or anyone you know be interested in it? It's in Ukiah, CA

Location: Somewhere between Heaven and Hell... But it is really hot here on Earth...
It is NOT "destroyed" like a VW TDI might be. THIS engine has a designed failure mode when the timing jumps that will protect the engine and is recoverable.

That said - how many miles on the engine / vehicle?

If you weren't aware, I'm the traveling CRD tech. This is the ONLY vehicle I work on and I've helped over 200 of them now. I'd be happy to discuss working on yours, just send me a message and we can go from there.

I offer three primary services, and each successive level includes everything from the one before - because the labor completely overlaps. The prices do not stack, it is simply the price for the chosen level, and then travel expenses. I bring everything needed for the work, and require nothing other than the Jeep in a vaguely-level parking place. Indoor spaces are appreciated but not required. The CRD IS a reliable platform once the (relatively few) design flaws on the engine are resolved, after that it is just regular "Jeep stuff" and things that every car needs.

If you find one that has already had my Level 3 service done to it, the engine will be reliable for at least the next 200k miles. The issues and their approximate miles however, are:

100k miles or 6 years: The timing belt and water pump needs to be changed. If this cannot be PROVEN with either a sticker or receipt for parts / labor... Then it has not been done. MANY people sell or trade the vehicle rather than pay for this service, which is why it must be PROVEN to be trusted that it has been done. Not doing it risks the rocker arms (designed failure point) and that raises the repair cost. Unlike a VW, the head is not damaged when the timing jumps or the belt breaks. This is my "Level 1" service.

130k-150k: Factory head bolts weaken and allow a head gasket leak to develop. The first indication of this issue is frequent "low coolant" alarms. ARP studs are a cure, but must be installed BEFORE the leak presents itself. A simple test can show whether the leak is happening. This is my "Level 2" service and includes level 1.

~200k, but could be anywhere from 150k and above (more common above 200k) is exhaust valve failure. This WILL result in severe engine damage and CANNOT be accurately predicted. There is no warning for when this will happen. The valves reach a fatigue wear point around 300 billion cycles and the alloy in the stem fractures in an instant, dropping the valve into the cylinder. The head and piston are destroyed and MAY jam the piston sideways in the sleeve. IF the piston and sleeve are not jammed, the engine IS rebuildable. But it is much better to prevent rather than let this happen. This is my "Level 3" service and includes everything from 1 and 2 and a lot more.
